[0076] like Figure 6 , Figure 7 and Figure 8 As shown, the stacking and pushing device 5 includes a card pushing head 51 and a card receiving platform 52, the card receiving platform 52 is connected to the card outlet of the card feeding device 4 and is slightly lower than the card outlet of the card feeding device 4, the card pushing head 51 and the card inlet of the card storage slot 71 are respectively located on the opposite sides of the card receiving platform 52, the card receiving platform 52 and the card pushing head 72 are respectively located on both sides of the card pushing head 51, when the card receiving platform 52 receives the first mahjong tile 10 delivered by the card feeding device 4, then the card receiving platform 52 descends and makes the upper surface of the mahjong tile 10 on the card receiving platform 52 not higher than the card outlet of the card feeding channel, then the card receiving platform 52 receives the second mahjong tile 10 delivered by the card feeding device 4 and stacks them into a pile, and the card pushing head 51 pushes the stacked mahjong tiles 10 on the card receiving platform 52 onto the card storage slot 71.

[0077] Among them, the first way for the card pushing head 51 to push the mahjong tiles 10 on the card receiving platform 52 to the card storage slot 71 is: when a pile of tiles is stacked on the card receiving platform 52, the card receiving platform 52 rises to the initial position, and then the card pushing head 51 pushes the mahjong tiles 10 to the card storage slot 71, and then the card receiving platform 52 waits for the next round of stacking tiles.

[0078] The second way in which the pusher 51 pushes the mahjong tiles 10 on the card receiving platform 52 onto the card storage slot 71 is: when a pile of tiles is stacked on the card receiving platform 52, the pusher 51 directly pushes the mahjong tiles 10 onto the card storage slot 71, and then the card receiving platform 52 rises to the initial position to wait for the next round of stacking.

[0079] In the embodiment of the present application, the card pushing head 51 uses the first method to push the mahjong tiles 10 on the card receiving table 52 onto the card storage slot 71.

[0080] like Figure 2-5 As shown, the push-up card loading device 6 and the card-lifting assembly in the card picking and transporting system in the same group are both located on the adjacent two sides of the shuffling plate 3, the card-lifting assembly is located on the inner side of the push-up card loading device 6, and the card-discharging direction of the first card-discharging port of the card storage slot 71 is rotated at an angle greater than 45° and not greater than 135° in the clockwise direction compared to the card-discharging direction of the second card-discharging port; further preferably, the card-discharging direction of the first card-discharging port of the card storage slot 71 is rotated at an angle greater than 75° and not greater than 105° in the clockwise direction compared to the card-discharging direction of the second card-discharging port.

[0081] In other embodiments, the push-up card loading device 6 and the card-lifting assembly in the same group of card picking and transporting systems can also be respectively located on the same side of the shuffling plate 3, and the card-lifting assembly is located on the inner side of the push-up card loading device 6, and the card-discharging direction of the first card outlet of the card storage slot 71 is rotated by an angle of no more than 45° in the clockwise or counterclockwise direction compared to the card-discharging direction of the second card outlet; further preferably, the card-discharging direction of the first card outlet of the card storage slot 71 is rotated by an angle of no more than 15° in the clockwise or counterclockwise direction compared to the card-discharging direction of the second card outlet.

[0082] In this embodiment, the slope card-loading device 7 also includes a card-lifting component. The specific structure of the card-lifting component can be found in patent documents with publication numbers CN201906453U, CN201949619U, CN102133480A, CN103861280A and CN204699375U. Generally speaking, one party's card-lifting component includes a card-lifting bracket, a card-lifting support plate 73 and a card-lifting motor. The card-lifting bracket is provided with a card-lifting slot, the card-lifting support plate 73 is located at the upper part of the card-lifting slot, and one end of the card-lifting support plate 73 is installed on the card-lifting slot, and the other end of the card-lifting support plate 73 can move and is driven up and down by the card-lifting motor through a transmission mechanism such as a cam or a card-lifting rocker arm. The card-lifting bracket is also provided with a sensor C for detecting the position of the card-lifting support plate 73, for example, two upper and lower Hall elements or photocells.

[0083] When the movable end of the card lifting support plate 73 descends, the movable end of the card lifting support plate 73 is connected to the card storage slot 71. At this time, the card storage slot 71, the card receiving platform 52 and the card lifting support plate 73 together form an inclined card loading channel for mahjong tiles 10, and the card pushing head 51 can be moved in and out of the inclined card loading channel; this is arranged because before the card storage slot 71 and the card receiving strip 61 are full of mahjong tiles 10, the card pushing head 51 needs to push the mahjong tiles 10 toward the card storage slot 71 and onto the card receiving strip 61 along the card storage slot 71, so the card pushing head 51 is located in the inclined card loading channel, when the card storage slot 71 and the card receiving strip 61 are full of mahjong tiles 10, the inclined card loading device 7 pushes the mahjong tiles 10 in the card storage slot 71 onto the tabletop, if the card pushing head 51 is located in the inclined card loading channel, it will block the passage of the mahjong tiles 10, so the card pushing head 51 is no longer located in the inclined card loading channel.

[0084] The first way for the pusher 51 to move out of or into the sloped card loading passage is that when there are enough mahjong tiles 10 in the card storage slot 71 and on the card receiving strip 61, the pusher 51 rises or falls relative to the sloped card loading passage.

[0085] The second way for the pusher head 51 to move out of or into the sloped card loading passage is that when there are enough mahjong tiles 10 in the card storage slot 71 and on the card receiving strip 61, the pusher head 51 moves horizontally to the left or to the right relative to the sloped card loading passage.

[0086] The third way for the pusher head 51 to move out of the ramped card loading channel is that when there are enough mahjong tiles 10 in the card storage slot 71 and on the card receiving strip 61, the pusher head 51 can be turned over in the card pushing direction to move out of the ramped card loading channel.

[0087] In this embodiment, the first card outlet and the second card outlet of the card storage slot 71 are located at the same height; such a configuration can facilitate the card pushing head 51 and the card pushing head 72 to push cards.

[0088] In another embodiment of the present application, the second card outlet of the card storage slot 71 is higher than the first card outlet.

[0089] In this embodiment, the card pushing head 72 has multiple card pushing parts on one side close to the card raising support plate 73, and these multiple card pushing parts respectively contact two mahjong tiles 10 stacked up and down in the same pile, among which the card pushing part contacting the lower mahjong tiles 10 protrudes from the card pushing part contacting the upper mahjong tiles 10.

The first card loading motor drives the card loading push head 72 to move through the synchronous wheel and the synchronous belt, and then drives the card loading push head 72 to move from the first card pushing position to the second card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61, and drives the card loading push head 72 to move from the second card pushing position to the first card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card lifting support plate 73.

[0092] The second embodiment: the card loading drive mechanism adopts a chain to drive the card loading push head 72, including a first card loading motor, a gear, a chain, and a chain track installed on the card loading bracket, the gear is fixed on the output shaft of the first card loading motor, the chain is meshed with the gear, and a card loading push head 72 is fixed at one end of the chain, the first card loading motor drives the card loading push head 72 to move through the chain, and then drives the card loading push head 72 to move from the first card pushing position to the second card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61, and drives the card loading push head 72 to move from the second card pushing position to the first card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card lifting support plate 73.

[0093] The third embodiment: the card loading drive mechanism can also use a wire rope to drive the card loading push head 72, including a first card loading motor, an active reel and a wire rope installed on the card loading bracket. The first card loading motor is fixed on the card loading bracket and is located on the inner side of the card storage slot 71. The active reel is driven to rotate by the first card loading motor. The wire rope is connected to the active reel after winding through multiple guide wheels and the card storage slot 71. The card loading push head 72 is fixed on the wire rope. When the first card loading motor moves the wire rope through the active reel, the card loading push head 72 moves on the card loading track, thereby driving the card loading push head 72 to move from the first card pushing position to the second card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61, and driving the card loading push head 72 to move from the second card pushing position to the first card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card lifting support plate 73.

[0094] The fourth embodiment, as Figure 2-5As shown, the card loading drive mechanism adopts a rocker arm to drive the card loading push head 72, including a first card loading motor and a card loading push rod 76 installed on the card loading bracket. The card loading push rod 76 rotates along its positioning end as the axis, and the card loading push head 72 is installed on the movable end of the card loading push rod 76. The first card loading motor drives the card loading push rod 76 to swing back and forth, thereby causing the card loading push head 72 on the movable end of the card loading push rod 76 to reciprocate along the card storage slot 71, thereby driving the card loading push head 72 to move from the first card pushing position to the second card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61, and driving the card loading push head 72 to move from the second card pushing position to the first card pushing position and push the mahjong tiles 10 in the card storage slot 71 onto the card lifting support plate 73.

[0095] In this embodiment, when the card-loading push rod 76 drives the card-loading push head 72 to rotate clockwise, one side of the card-loading push head 72 pushes the multi-pile mahjong tiles 10 in the card storage slot 71 onto the card receiving strip 61; when the card-loading push rod 76 drives the card-loading push head 72 to rotate counterclockwise, the other side of the card-loading push head 72 pushes the multi-pile mahjong tiles 10 in the card storage slot 71 along the card lifting support plate 73 onto the mahjong machine table 1.
